    Thanks for this reply!

    Indeed, as the link you provided says, for Aarch64 the flag "asimd" stands for NEON too.

    I have just compiled OpenCV with neon and it was imported without any problems.


    Many thanks!

  2. Hello,


    I've been trying to compile armbian for my OrangePI Zero Plus H5 with NEON and VFPV support for OpenCV .


    If I use the providede default image from OrangePI I can see that NEON and VFPV are enabled with lscpu command. 


    When compiling armbian from source or downloading the pre-compiled images, I see the following:


    root@orangepizeroplus2:~# lscpu
    Architecture:        aarch64
    Byte Order:          Little Endian
    CPU(s):              4

    NUMA node0 CPU(s):   0-3

    Can somebody help me enabling NEON and VFPV flags?
